Plant Sentry™
Plant Sentry is designed to protect both consumers and the nursery trade from invasive plant pests and diseases. Sites that display the Plant Sentry protection badge are protected from consumers buying and nurseries shipping material carrying invasive pests and diseases.
This proprietary eCommerce software prevents the shipment of a restricted plant to each state. The Plant Sentry system includes a shipment certification program. The Plant Sentry Compliance Officer works closely with NatureHills.com and each nursery or fulfillment center to ensure only compliant plants are sold to customers.

Advance Crocus Bulb plants (Crocus 'Advance'), 15 pack, are a welcome little cold-resistant darling that are just the flower to help usher in spring! Advance features unusual buttery yellow blooms inside with contrasting purple-striped sepals on the outside! Giving each blossom a two-tone effect!
Often shooting up and blooming before the foliage has had a chance to catch up, Crocus are among the first spring bulbs to emerge after a long, dreary winter! Sometimes even poking up through the melting snow. That's just how cold-hardy these little troopers can be! If you can get down on your hands and knees, you'll enjoy the mild, sweet fragrance they emit! You'll also enjoy the early pollinators that find them!
Browse our entire collection of Crocus, or filter your options by growing zone, sun exposure, color and other factors.
Planting and Application:
Use these very low-growing perennial bulbs and their grassy foliage as edging and for early spring color in even the smallest places! Containers and planters that are protected from fully freezing will be perfect for creating an early-season blooming display! Wind throughout garden beds and among larger perennials or shrubs, without worrying the bulbs will interfere with larger roots or vice versa!
Technically known as corms, Crocus bulbs should be planted in early fall before the ground freezes. This can be anywhere from September to November, depending on your growing zone and climate. Plant in a sunny site near a wall or foundation for earlier blooms, or in a shadier location for later emerging bulbs.
- Fragrant Buttery Yellow Blossoms
- Purple Stripe Outside of Sepals
- Dark Green Grassy Foliage Clumps
- Try Forcing for Winter Décor
- Great in Containers, Edging, Around Tree Roots
#ProPlantTips for Care:
Growing zones 3 to 8 can leave Crocus plants in the ground, or even in a large planter. This is possible because Crocus bulbs require at least six to eight weeks of what's known as 'chill hours' before they will sprout.
- Full Sun to Part Shade
- Moderately Moist Enriched Well-Drained Soil
- Cannot Tolerate Soggy Conditions
- Cold-Hardy Perennial Bulb
- Plant ~2-6 Inches Apart
